To aZLwkom it may camera:

Be it known that I, ALBERT C. MURPHY,

a citizen of the United States, and resident struction of a dumping carwhich may be operated from one or both ends of the car for dumping theload to either side of the track, and providing automatic side doors forthe body for releasing the contents and guiding them to a distance fromthe road bed when the body has been tilted into a discharging position.

My invention consists of certain constructions which are fully describedhereinafter and more particularly defined in the claims, and these willbe better understood by reference to the drawings in which Figure 1 is aside elevation of a dumping car embodying my improvements; Fig.2 is aplan view of the same with the tabs over the end platforms removed; Fig.3 is an enlarged side elevation of the left hand portion of Fig. 1showing the structure more in detail; Fig. 4 is a transverse section ofthe vehicle on line mw 'of Fig. 3; F ig, 5 is a transverse sectionalelevation on line y-y of Fig. 3; Fig. 6 is a cross sectional viewillustratin the details of the locking device or latch or holding thedoors closed; Fig. 7 is a sectional elevation on line tt of Fig. 3showing the means for operating the car body; and Fig. 8 is a sideelevation with a portion in section of the operating means for tilt-ingthe body.

2 is a girder frame extending throughout the length of the car andconstituting the main frame of the car. Near each end this main frame'isprovided with the pivot block 3 to which the trucks 4 (diagrammaticallyindicated) are pivoted and which may be of any suitable construction.Furthermore, adjacent to the pivot blocks the main frame is providedwith lateral .extensions 2 at each side and which have the shoe portions3 adapted to rest upon the truck frame, the said parts 2, 3 and 3 beingin connection with the girder frame 2 constituting the bolster of themain frame for transmitting the weight of the car upon the truck frame.

Each end of the main frame 2 is provided lines in Figs. 4 and 5.

on its under side with rockers 1 shelter during transportation and whenoperating thepower transmitting mechanism 25, employed in connectionwith the tilting of the car body 7. Preferably there is one of theseplatforms and operative mechanism at each. end of the car, but this isnot essential as the car body may be operated wholly from one end of-the car if so desired.

The car body is preferably formed of a longitudinal box body of sheetmetal having side openings for the discharge of the contents, saidopenings being normally closed by hinged doors 9, the latter beinghinged at 10 to the lower sides of the body and deta'chably locked inclosed position at their upper' ends by latches or looks 11 carried uponand operated by rock shafts 12. These rock shafts are suitably.journaled in bearings carried upon the top side rails 7 of the body,and as shown in Fig. .6 the latches 11 are loosely hinged upon the shaft12 and are provided with elongated slots 11 into which project studs 12of the shaft, said construction being such that the latch 11 may belifted by hand into the dotted position (Fig. 6) when closing the doorwithout the rocking shaft 12, whereby each door may be closed by theworkmen without having to manipulate the car body. When the doors are tobe automatically opened the" rock shafts 12 rock, and this through thestud 12 turns the latch 11 into the dotted position to release the door9 and allow it to fall as indicated in dotted There may be a number ofdoors 9 on each side of the body according to its length, so as toreduce the amount of weight which would have to be lifted by the workmenin closing the doors at any one time. When the doors drop into the openposition they are held in oblique relation by means of chains 9 andsprings 9",the latter being connected to the top side rails 7 and theformer connected with the doors near their free ends. When the doordrops by gravity after being released its inertia on assuming theposition indicated in dotted lines is taken up by the elasticity of thesprings 9 and in its open position acts as a chute or guiding apron forguiding the contents of the load of the body to a distance away from thetrack upon which the vehicle runs. The body 7 is which rock upon thetransverse beds 18, the rockers 17 being preferably provided with teethand rovided Patented May 1, 1917.

the beds with apertures for engagement by the teeth and which preventlateral abnormal displacement of the rocker upon the bed. The rockersare so made that as the said rod telescoping witha tube 15, the lowerend of which is hinged at 16 to the bolster of the truck frame asclearly indicated in Fig. 4. Similar mechanism is arranged to operate onthe other rock shaft for controlling the doors on the opposite side ofthe body as indicated in dotted lines in Fig. 1, said mechanism beingarranged at the distant end of the body. By thismechanism it is evidentthat when the body is tilted the rising side of the body will draw therod 14 upward to a greater or less extent out of the tube 15 withoutrocking the rock shaft, but

on. the descending side of the body the lower end of the rod l l willreach the bottom of the hole in the tube 15 and the further depressionof the body will cause the arm 13 to be locked relative to thebody andthis will impart a rocking motion to the shaft 12 and the latches orlooks 11 to raise them and liberate the door as indicated in dottedlines.

When the body is returned to its horizontal position the locks orlatches 11 will have re.

turned to their normal positions shown in Figs. 4 and 5 and at this timethe doors 9 may be lifted and moved back into closed position, but toenable this to be done the locks and latches 11 must be raised to permitpassage of the free ends of the doors and this IS permitted by havingthe locks or latches free to be lifted on the rock shaft 12 by handmanipulation as heretoforedescribed in connection with Fig. 6. e r

The body, as heretofore stated, is a box shaped frame preferablystrengthened by suitable longitudinal girders 7*, (Fig. 5), thetransverse rockers 17 being securely positioned upon the central girder7 d and between the two longitudinal girders .7. Moreover, the. body isreinforced transversely by means of transverse girders 8 which, as shownin Fig. 1, are three in number and these extendpreferably about half wayup throughout the main portion of their length and wholly up to theupper portion of the body at each of their lateral ends, saidconstruction being more fully illustrated in Fig. 5. Thesetransverse girers act as divisions to properly guide the load in disends of the car.

larly when the car tilted if so 7 and 7* arm Bloutward to release thelever 33 lation and adapted to be operated from both At each side of thelongitudinal frame 2 and journaled in the lateral extensions 2 thereofare the longitudinal shafts 19, said shafts extending to the platformsat each end of the girder frame and provided with one or more pinions20, preferably held in position-within the lateral extensions 2 of thegirder frame. These pinions engage racks 21 which are hinged at theirupper ends at 22 to the tilting body respectively at each side of thetransverse rockers. These racks 21 are preferably held into engagingposition with the pinions by the guide rollers 23 which are alsojournaled in the lateral extensions 18 of the girder frame. Theselateral extensions 18 of the girder frame are preferably reinforced bythe transverse girders 2 which extend the full width, of the girderframe. At' one end of each shaft 19 is a sprocket wheel 24 and at theother end is a lock wheel 31 having a notch 32 in its periphery. Thesesprocket wheels and locking wheels are so arranged that there is one.ofeach under each of the platforms 5 so that the car body may be tiltedby'the shaft having the sprocket wheel under the platform at which theoperator stands, and the car-body may be locked by a locking lever 33engaging the notch in the locking wheel 31 under the said platform onthe other of the shafts 19. This locking of the car body may be employedmore particubody is in the horizontal position during transportation,but it may be also temporarily locked when the body is desired. As shownin Figs. 7 and 8 the locking lever 33 in itslocking position has thehandle end raised andsupported over a lug 35 on a spring arm 34 which isbolted to the main frame 26 of the power applying devices which areemployed I to tilt the body. Assuming the parts are 1n thefpositionshown in Figs? and 8 with the horizontally positioned fortransportation, and it should be desired to tilt the body fordischarging the load at the place of destination, the first operationwould be to pull the upper end of the spring and permit it to drop intothe position indicated in dotted lines in Fig. 7 in which it isdisengaged from the locking wheel 31. The car car body body may then betilted by rotating the shaft 19 having the sprocket Wheel and whichpreferably operates upon the rack 21 to push upward, it being moredesirable that the tilting shall be produced by a thrust rather than bya pull. I, however, do not restrict myself in this respect.

It will now be seen that if the hand Wheel 29 be rotated the speedreducing gears 28 will rotate the sprocket pinion 27 and this, throughthe sprocket chain 30, is made to rotate the sprocket wheel 24 and itsshaft 19 to tilt the body. Owing to the tendency of the loaded body toreturn to its normal position it is desirable that the hand wheel andpinion shall be held against rotating backward, and yet have provisionwhen desired for rotation in either direction. To provide such means Iprefer to employ a detent wheel 36 which may be varied much like anordinary gear. Engaging with this detent wheel 36 is a pivoted pawldevice 37 which has engaging teeth arranged to operate in bothdirections. Pivoted to the main frame 26 above the pawl is an arm 38 andto this arm is connected a spring 39 whose other end is connected withthe pawl 37 above its pivotal point. When the arm 38 is thrown into theposition shown in Fig. 7 the spring pulls the pawl into engagement atthe right hand side of the detent wheel and it will now b seen that thesaid wheel may be rotated to the right like the hands of a watch, butcannot rotate in the opposite direction. If, however, the arm 38 isthrown over to the left of the main frame 26, then the other side of thepawl comes into contact with the detent wheel and the hand wheel thenmay rotate freely to the left or in a reverse direction to the hands ofa watch and will be locked against rotation in the other direction. Itis therefore possible for the operator to throw this arm 38 in eitherdirection according to whether the wheel is required to rotate to theright or to the left to suit the particular tilting of the car bodywhich is required. It is to be kept in mind that in the tilting of thebody one of the shafts 19 rotates in one direction and the other in theopposite direction so that if an operator were to stand in front of thehand wheels in each of the-two cabs, the two hand wheels willnecessarily rotate in opposit directions, and if the car" is to beoperated solely from one end, then th operator mustfir'st disengage thelooking lever 33 at the opposite end of the car and also throw the arm38 at that end so that it will permit the freedom of movement of thehand wheel, and then he may operate the car body from the opposite endof the car under perfect control. If the load is very heavy and it isdesirable to operate the tilting from each end of the car, then anoperator will be on each platform and will accordingly manipulate theparts to cooperate in the operation of the body. -It will thus be seenthat the body may be tilted or rocked from each end of the car, but I donot restrict myself to this use of double power mechanism and doublelocking mechanism as it is manifest that if desired the car may haveonly one oper ating platform and one set of operating mechanism for thetwo shafts, one of which would act as a locking shaft and the other as atilting shaft. It is also manifest that with the two platforms theentire operation of the vehicle body may be conducted with the use ofone shaft and the pinion and rack connections, as in this case thisshaft may b locked in by the mechanism at one end and may be operatedwhen unlocked by the mechanism at the other end, these variations beingwithin the capacity of the engineer in designing and using the car.

It is also evident that while I have shown no means for operating thecar body, any of the usual and well known power devices may be employedin lieu thereof if so desired, but for ordinary purposes hand operatedmeans is found to be entirely satisfactory.

In the tilting of the body upon the main girderframe the rockers andbeds are so constructed that the center of gravity of the loaded bodymoves laterally commensurate with the shifting of'the axis ofoscillation between the rockers and beds so that at all times a minimumpower will be sufficient to rock the car body. The means of pivoting androcking the car body may, however, be varied without deviating from theessential requirements of the invent-ion.

I have shown my improved car construction in the form which I have foundwell adapted for commercial requirements, but I do not restrict myselfto the minor details as these may be varied in many ways withoutdeparting from the spirit of the invention.

Any matters shown and described in this application relating to thetilting box body and the means for operating the same, and also to therocker means such as the limit-- ing abutments therefor, and not claimedherein, form subject matter of my application Ser. No. 775,462, filedJune 24, 1913; and neither do I make claim in thisapplication to the boxbody having the intermediate transverse divisions and with side doors,as the same also has been claimed in my said application Ser. No.775,462.
